Lifespan, longevity, and ageing

Observations: Very little is known about the longevity of sunfishes, though given their their large body size and reproductive output it is possibly they are long-lived. They can lay 300,000,000 eggs. Anecdotes suggest they can live more than 10 years in captivity, but possibly much longer (http://www.oceansunfish.org/).
